1. Harry Reid vs. Mitt Romney
This story generated more than 10,000 comments today, dominating conversation on the site. Republican sources say they're in a Catch-22 situation on how to reply to Senate Majority Leader Harry Reid's claims that GOP presidential candidate Mitt Romney went 10 years without paying taxes. They either play along with Reid and keep the conversation going, or they refuse to participate and risk rousing suspicions. Some of our readers say this situation is justified, especially after all the requests for President Barack Obama's birth certificate, while some other readers say they think Reid is playing dirty with Romney to harm his candidacy.
What's Reid really thinking?
NoGasBags: "Harry's a genius. The only way for this issue to die down is for Romney to release the returns and disprove him. There's obviously something in there. Romney's too smart to evade taxes, but by some form of manipulation he may have avoided paying them for several years. I'd say keep the issue going. It's one more issue of secrecy in regards Romney, his ideas, plans and faith. Go too it Harry!"
oddjob3422: "A genius indeed. The move might be politically effective, but it's just another example showing how Harry Reid is the biggest embarrassment in our entire government. The man is absolutely reprehensible to abuse his power as Senate majority leader to hawk his unsubstantiated claims. Doubtless there is someone else pulling the strings, though, because Reid can hardly put together a sentence on his own. To watch the man talk on the Sunday morning political shows is to cringe in embarrassment. I didn't see the footage of his asinine Senate floor screed, but I have little doubt that he was, as usual, looking down at a cue card, slowly and haltingly sounding out words written by others. This is what we are down to – outright slander being tolerated, and the U.S. Senate floor being used as the vehicle to spread it."

The CNN Daily Mash-up is a roundup of some of the most interesting, surprising, curious, poignant or significant items to appear on CNN.com in the past 24 hours. We top it with a collection of the day's most striking photographs from around the world.
Simon DeDeo is an Omidyar Fellow at the Santa Fe Institute, where he researches theoretical biology and physics. He tries to explain why space exploration, such as this week's landing of a rover on Mars, strikes such a chord with so many of us.
Maybe we saw something deeper in the successful landing of Curiosity. We experienced - even if vicariously - a group achieving unambiguous excellence. In a nation where a city like Detroit can nearly collapse, where consensus on important policy issues seems far off, where some of the "best and brightest" minds of finance have built fragile institutions, how is it possible that a large cast of scientists and engineers can pull off such a remarkable task?
Although computing power has made much of our progress in space possible, the death of the conventional personal computer may be imminent as technology marches forward. This prospect does not sit well with some of our readers, such as this one:
Never, I tell you ... Never. I will chain myself to my PC. They can have it when they pry it from my cold dead hands. It's constitutional, the right to bear PCs.
Readers also turned a jaundiced eye toward the news that American judo athlete Nicholas Delpopolo had been thrown out of the Olympics after a failed drug test he blamed on inadvertently eating food that had been baked with marijuana.
It appears the marijuana also caused him to lose any semblance of rationality.¬† That has to be the worst excuse I've ever heard, except for 'the dog ate my homework'.¬† If you want to be a pothead, live with the consequences.¬† "Oops, I ate a pot brownie."¬† This guy's credibility just went in the toilet.
There's a good restaurant in East Atlanta Village called Holy Taco. Maybe they could work out some kind of a deal with La Amistad Adult Daycare in Beeville, Texas, where Ernesto Garza discovered a startling image on his breakfast taco. CNN affiliate KENS has the rest of the story.
CNN iReporter Sonny Gill, 30, of Chicago is a member of a Sikh community in Palatine, Illinois. He took part in a vigil to honor the victims of the mass shooting at a Wisconsin Sikh temple.
"I personally went to the vigil to support our community and family of Sikhs who are going through this hard time. And to show that their strength is still here, regardless of these senseless acts," he told CNN. "The biggest thing that stuck out to me was that we received prayers and heard from various community members from different backgrounds and religions. That truly showed how united we are as Americans and that one person's act will not deter us from continuing down our path of welcoming peace."

Gunmen attacked a church in the central Nigerian state of Kogi, killing at least 19 people, a military official said Tuesday.
Among the dead was the pastor of the Deeper Life church in Okene, Lt. Col. Gabriel Olorunyomi said.
No one has claimed responsibility, but immediate suspicion fell on the militant Islamic group Boko Haram, which has carried out similar church attacks in the past.
An eyewitness told CNN that the attackers were carrying sophisticated firearms and shot randomly at the members of the congregation gathered for Bible study Monday night. Blood flowed through the church as bodies fell limp, the witness said.FULL STORY

Juliette Touma said all of those people part of the U.N. mission in Syria have been moved back to Damascus amid growing violence.
"This is a temporary move back to Damascus and we still hope to return the team when the security situation allows," Touma said.

Syria's president welcomed a top official Tuesday from Iran, a friend and ally of the much reviled and increasingly isolated government in Damascus.
Saeed Jalili, secretary of Iran's Supreme National Security Council, met with President Bashar al-Assad to discuss resolving the 17-month-long civil war and rescuing several Iranians who were kidnapped over the weekend.
State TV showed footage of Jalili and al-Assad in the first video of the president that has surfaced since last month.
Jalili called on Syrians to sit down and forge a solution to the crisis, which morphed into a nationwide uprising and civil war after government forces cracked down on peaceful protesters in March 2011.FULL STORY

11:40 am ET - Romney in Illinois - GOP presidential candidate Mitt Romney takes his campaign to Elk Grove Village, Illinois, where he'll discuss the economy at a manufacturing plant.
Police in Florida are trying to solve a mystery surrounding a man arrested with a enormous stash of fake military, law enforcement and medical paraphernalia including federal badges, police radios and even a full NASA flight suit and helmet.
In all, Roy Antigua had about 200 suspicious items when he was arrested earlier this month, said James Steffens, chief of the New Port Richey Police Department.
The cache found in Antigua's two homes and Cadillac Escalade included diplomatic license plates, dozens of fake identification cards from the Department of Homeland Security, Immigration and Customs Enforcement, Department of Defense, CIA and NASA. The suspect also had access badges to hospitals around Florida, doctor and nurse scrubs, a respiratory technician badge, police blue lights and access stickers to Coast Guard bases around Florida, Steffens said.
Authorities are wondering if Antigua, 52, was a frequent guest at costume parties or if he was hatching something sinister.FULL STORY
James "Whitey" Bulger, the reputed former Boston mob boss who was arrested last summer in California, will take the stand when his murder trial starts in March 2013, his lawyer said Monday.
Bulger faces 19 murder charges, as well as charges that include extortion, money-laundering and narcotics distribution.
"At this point in his life, his goal is to have the truth come out regarding how he was able to act with impunity for so long in the city of Boston," his lawyer Jay Carney told CNN affiliate WCVB.
The defense had initially moved to dismiss the case, saying that Bulger had been given immunity by federal agents working to infiltrate Irish and Italian mobs in Boston three decades ago.
Bulger's lawyers had repeatedly argued that the amount of evidence, some 300,000 documents and surveillance tapes, made the March trial date unrealistic. But Carney said Monday that the defense planned to take another tack.FULL STORY

Quick. Think of a white supremacist group.
What comes to mind? The Ku Klux Klan during the 1920s? Maybe the Nazis in World World II?
Hundreds of white supremacist groups are active in the United States today and are experiencing a kind of resurgence.
They are in the spotlight this week in the wake of a deadly shooting at a Sikh temple outside Milwaukee. Authorities have said they are looking into whether the alleged gunman, who was killed, had ties to a white supremacist group.
"I know they're out there. I try not to alarm the public too much, but it's something that really needs to be taken a hold of now because more and more we see facts coming out that this is happening more often and more often, and it's not going to stop anytime soon," said David Gletty, who worked as an undercover informant on extremist groups for the FBI.FULL STORY
